In this episode, host Andy is joined by Paul to provide a comprehensive overview of confidential computing - what it is, why it's important, and how it's being implemented in cloud platforms like Microsoft Azure.  

Key Takeaways: 

• Confidential computing aims to protect data while it is being processed by the CPU or stored in memory, supplementing traditional protections like encryption of data at rest and in transit.
• Confidential computing can enable use cases like confidential AI model training, secure multi-party data sharing, protecting sensitive data in cloud VMs, and securing blockchain/distributed ledger systems.
• Establishing a root of trust from the hardware up through the software stack is critical for confidential computing.
